Inscribed_Rectangle package provides 2 low level computer vision / image analysis functions able to locate largest square or rectangle inscribed inside arbitrary shape defined by a binary mask (black and white image). Only rectangles with vertical/horizontal edges are considered. The functions proved can be used as tools for larger image segmentation problems

This code is not working for finding maximum rectangle inside an airfoil shape.

Mustafa Khries, I am sorry but it sounds like you need to brush up on basic MATLAB skills. I am sure you can find websites that will be more helpful. You can also try to run and modify my tutorial.

Hello,
I'm trying to find the largest rectangle in an airfoil shape, I don't know how to get the image of the airfoil in matlab, and use the code for finding the rectangle. help please.

The code produces an incorrect result if the input is an entirely white image. Changing line 25 of FindLargestRectangles.m into "if max(I(:)) == 1" appears to solve this problem.

No, in the the problems I was working on the rectangles are always parallel to the edges.

Can it find tilted rectangles, not aligned with the image edges?
